Lifelong Lube?

This bulletin applies to 2000-2010 Cadillac Escalade models.

The service information and owners manual do not show a service interval for the 7.6, 8.6, 9.5, 9.75, 10.5 and 11.5-inch rear axles with or without G80 locking differential.

According to Cadillac, these axles do not need to be serviced under normal operation due to the synthetic fluid that is installed at the factory.

As long as the fluid level is correct, there’s no need to change the gear lube.
